To all whom it may concern: 3

Be it known that I, ALEXANDER S. SPIEGEL,

a citizen of the United States, and resident.

of Chicago, Illinois, have invented certain new and useful Improvements in Apparatus for Producing Shingles, of which the followin is a specification.

y invention relates to an apparatus for producing shingles of the composition type very quickly and with a minimum amount of waste.

My invention aims to produce shingle strips or slabs out of a roll of fabric which is position material and this is fed by feeding mechanism of usual and ordinary construction, as shown at b, slitters being also driven by this mechanism as shown at c, fori slitting the fabric centrally. A die plate (1 receives and supports the fabric as it passes above it and as the mechanism is adapted to feed the fabric continuously, suitable dies 6 supported on shafts f are adapted to be rotated in connection with the die plate to die out a unit of the shape shown by the die leaving between the two dies two additional units, which by reason of the central slit, are automatically produced at the same time that the marginal units are produced. After the dies have acted the fabric is fed along and the end die g will cut ofi the central units at the dotted line it, thus completing four sections.

The laterally operating dies 6 cut out the edge sections and cut out the slots of the center sections, the dies being recessed at e to form corresponding slots in the side sections. The only waste is in the portions of the fabric within the slotted sections 6 of the dies and that made by cutting the slots of the center sections.

What Iclaim is:

In combination with a roll supporting the fabric, feeding means for the fabric, means for slitting the fabric into longitudinal outer and central sections, a die plate over which the fabric passes and laterally operating dies comprising main sections having recesses e and portions adapted to form slots in the central sections and a cutter for severa ing the fabric transversely, substantially as described.
